Field Termination Modules

Single connector Passive Feed Through modules are available in tow versions: Standard FLKM modules and the Compact UMK versions.

he FLKM…/M/PLC modules offer a common minus potential to connect input or output devices with a shared return lead (sourcing devices).

The FLKM…/P/PLC modules offer a common plus potential to connect input our output devices with a shared supply leads (sinking devices).

Utilizing these types of modules allows for both wires of a device to be connected to the module. There is no longer a need to connect to a separate supply or return source.

Plugging in preassembled system cables on one side of the interface and discrete wire connections on the opposite side of the module makes the interface connection. As panel feed-through connections in control cabinets or machine parts, the DFLK 50/PLC connects 50 positions to screw terminals and the DFLK 50-HC… connects from either a 50 position ribbon connector or 4 - 14 position connectors to 64 position and a 40 position design D industrial hood connector respectively. Using COMBICON connectors, power to the hood can be connected separately from the ribbon cables.

The most dominant feature of the HEAVYCON plug connectors is their robust aluminum diecast housing. When these housings are locked, they correspond to a protection level of IP67.

Each signal path can be allocated an LED for signal identification. An active "high" on the input causes the LED to illuminate. The additional LED status display simplifies simulation, system startup and maintenance. For each sensor signal the modules offer the additional connection possibility of a common plus and minus potentials on the peripherals. The plus/minus supplies for the sensors are provided by separate input terminal blocks on the module. A green LED indicates that the operating source voltage is present.

These modules are also available in the Compact-Line with a width of 45 mm to provide a compact solution for connecting 3-wire devices.

The modules connect 14 or 50-position system cables via male ribbon cable connectors to screw connection terminal blocks.

Each channel is protected by a pluggable button fuse (Wickmann TR5 style). In addition to the terminal point for the signal, there is also the connection for a return conductor. This module contains a common minus potential for a two-wire system.

There are also fused modules available that utilize the popular 5 x 20 mm fuse. Some of these modules incorporate Blown-Fuse-Indication.

This module is also provided with short and long engagement catches to snap and lock the male and female connectors.

These modules guarantee the reliable conversion of low capacity output signals to drive motors, contactors, solenoid valves and other components for 8 to 32 channels. At the coupling level, the modules are responsible for signal amplification and electrical isolation between system potential and PLC controller.

The modules are equipped with pluggable electromechanical miniature relays. The two layer double contacts with hard gold plating enables universal application of 1 mA to 3A continuous current per contact.

Each relay channel is allocated an LED indicator for status display, simulation, system start-up and maintenance, via which the signal status "active high" is indicated. The supply voltage to the module is shown through a green LED.

These modules guarantee the reliable conversion of low capacity output signals to drive motors, contactors, solenoid valves and other components for 8 to 32 channels. At the coupling level, the modules are responsible for signal amplification and electrical isolation between system potential and PLC controller.

The modules are equipped with pluggable electromechanical miniature relays. Each of the relays are capable of delivering a constant current output of up to 5A at 250V ac.

Each relay channel is allocated an LED indicator for status display, simulation, system start-up and maintenance, via which the signal status "active high" is indicated. The supply voltage to the module is shown through a green LED.

The modules also include suppressor diodes to protect the control device that is connected to the coil side of the relays.

These modules guarantee the reliable conversion of low-capacity output signals to drive contactors, solenoid valves indication etc. for 8 to 32 channels. These interface modules take over the signal amplification and electrical isolation between the system potential and programmable logic control in the coupling level.

The modules are equipped with commercially available electromechanical miniature switching relays with two PDT contacts each. The relays used in this module are capable of switching.

Each channel is assigned an LED for status indication, simulation, system start-up and maintenance. A Yellow LED indicates the signal status "high active". A green LED indicates that the operating voltage for the coils is present.

In this way, the benefits of the pluggable and modular structure (flexible) of the PLC-RELAY system as a relay and optical coupler (solid state) interface are united with the fast and faultless PLC connection technology.

The PLC-V8 adapter is simply plugged into the bridge slots of eight PLC RELAYs aligned in a row. No additional tools are required! In this way, an 8-channel relay or solid state relay module with a construction width of less than 2 inches is created.

The use of electromechanical or semiconductor relays (solid-state relays) can be freely selected for each channel. The different adapters for input or output functions are marked with the endings IN or OUT.
