The IOM range of I/O modules are designed for use as local I/O within motor control cabinets or as remote I/O connected via RS485 Modbus. Typical applications include building automation control systems.
The 4DO module provides 4 independent 250vac/16A rated digital relay output channels each with change over contact configuration. Each digital output has a yellow LED which indicates the current status of the connected device.
The IP20 rated module may be plugged together with other IOM modules and fitted onto standard TS35 DIN rail or fitted directly onto a backplate using screw fixings. The cascadable design allows power and 2-wire RS485 Modbus communications to connect through without any extra wiring.Modbus address setting is by rotary switches which are easily accessible underneath the top cover. A bi-colour LED indicates thecommunications status. The 4DO module has one 2-wire RS485 port supporting a Modbus communications network connection to a JACE® controller.
