Outputs:
The RCI-200 has two form ‘C’ relay contact outputs and two 0-20mA analog outputs.
The relay contacts are capable of switching 120VAC, 10A or 240VAC, 6A. An energy
absorbing varistor is installed across each contact to limit switching transients. A
third relay contact acts as a communications fail indicator. If no communication
occurred within 30 seconds, this relay contact will energize. Upon re-established
communication this relay will de-energize again.
The two analog outputs are typically configured as 0-20mA outputs and can drive into
a 1000
Ω
load each, provided that the power supply to the unit is not below 24VDC.
The outputs are not isolated from each other or from the inputs. Care must be taken
when connecting the outputs to different devices so that no inadvertent ground loops
are established.
Output Calibration & Input Testing:
The outputs on the RCI-200 are factory calibrated and should not require any adjustments.
To
check the calibration of the outputs and relays use jumpers H1-7 & H1-8 as shown below to set them to
known states. If an output should require some adjustment, insert
jumper H1-8 only and turn the OUTPUT CALIB. trim pot until the output
reads 20mA.
If both jumpers are IN the analog and contact inputs are passed straight through to the analog and
relay outputs. This may help in troubleshooting input and output signals.
Make sure both jumpers are removed before resuming normal operation.
