DIRECT INTERFACE TO UNIVERSAL RELAY MODULE

For high amperage loads, DPS3300 series units can be used in conjunction with Universal Relay Module (Model RELAY-URM400/800) which provide up to eight 15 ampere relays. Both open collector and relay models can be interfaced directly to RELAY-URM400/800 units.

RELAY-URM400/800 series relay module is a very versatile instrument that is used for switching up to eight 15 ampere loads. In addition to the DPS3300 direct interface, RELAY-URM400/800 series relay module accepts low level input signals from PLCs, process controllers, indicators, motor starters, etc. Selectable input allows activation of output relays on direct acting or reverse acting signal. In addition to working with control/logic level signals, another very useful feature of RELAY-URM400/800 is activation of output relays on contact closure. The use of the RELAY-URM400/800 allows heavy loads requiring up to 15 amps to be controlled by the DPS3300 with minimal equipment & wiring.

Input and output connections for the RELAY-URM400/800 are made through euro style pluggable connectors which are conveniently located on the top and bottom of the unit. Screw in terminals allow for quick connect/disconnect of wires. The unit is housed in a versatile enclosure that can be configured for mounting on a DIN rail or on a wall. If desired, the same enclosure can be panel mounted with relay, AC and DC supply status visible on the front. LEDs on the front panel turn on when a relay is energized. Two different versions are offered in this series. First one is RELAY-URM400 that has four relay outputs. The second one is RELAY- URM800 that has eight relay outputs. (Future versions will also include 4-15A solid state relays). Both units come with a built-in universal power supply. It operates from 100vac to 240vac. This power supply provides power not only to the internal electronics and relays but has up to 20watts (5vdc) available for external applications by the user.
