The Define Instruments RIO-MOD-RTU distributed I/O station is capable of providing 16 isolated relay outputs and 16 digital inputs. The isolated relay outputs are Form C change over (10A 250VAC or 10A 30VDC) with a 1kHz scan rate. The relay state is software selectable and features an auto shutoff. The digital inputs have a 1kHz sample rate, an input voltage of 5 to 24V, and can be set to NPN (sink) or PNP (source). There are LED indicators on each of the relay outputs and digital input channels for commissioning and fault finding.
This unit can be used as a remote terminal unit for any Modbus system and supports the following Modbus function codes:
