DRM88RL Relay module, 8 inputs and 8 relay channels under 16A

The DRM88RL Relay module, 8 discrete inputs and 8 relay channels under 16 A. Unlike DRM88R, the module does not have built-in scripts, it has only independent inputs and outputs. Control under the RS-485 MODBUS.

•        The module has a housing on a 6 unit DIN rail with 8 discrete inputs and 8 relay outputs (up to 16A 230V each). Unlike DRM88R, the module does not have built-in scripts, only independent inputs and outputs. Controlling the module is possible via the RS-485 from a controller or by PC commands under the MODBUS RTU protocol.

The module has the following features:

•        the module has 8 discrete inputs;

•        the module has 8 relay outputs;

•        Each relay can commute up to 16A 250V. 7 relays have a group of C contacts (switching) and 1 relay a group of A contacts (short circuit);

•        the module connects to the RS485 bus via a 4-wire cable, including power;

•        the module supports the exchange protocol: MODBUS RTU;

•        the module can work together with the controllers: “RD” or industrial controllers;

•        Installation in an electrical board on a DIN rail, 6 DIN wide;

•        powering of the module from 12V to 24V.

When connecting to contacts of large inductive loads relay (contactors, starters) it is necessary to connect a snubber (damping capacitor) in parallel with the contacts.

Contact protection at inductive load.
