Protection
The voltage output is protected from short circuit. Also be aware that a short
circuit condition existing for too long of a time may cause damage on internal
circuits. The current output can be open circuit.
Communication mode
(RS-485)
ASCII/RTU mode.
Communication baud rates available:
4,800/9,600/19,200/38,400/57,600/115,200 bps. ASCII data format: 7-bit,
Even, 1 stop bit (7, E, 1).
RTU data format: 8-bit, Even, 1 stop bit (8, E, 1).
RS-485 cannot be used when connected to ELC MPU in series.
When connected to
ELC MPU in series
The modules are numbered from 0 to 7 with respect to their position from from
the controller. 0 is the closest to the controller and 7 is the furthest. Max. 8
modules are allowed per controller and they do not count agains the allowable
digital I/O.
