Hardware
Do not power unit and inductive loads with the same power supply even though there is enough
immunity in the OIS to withstand the transients present on these lines. Avoid using power supplies
with large capacitive outputs which may cause problems if power is cycled within a short time
period.
If wiring is to be exposed to lightening or surges, use appropriate surge suppression devices.
Keep AC, high energy and rapidly switching DC wiring separate from signal wires.
Connecting high voltages or AC power mains to the DC input will make unit unusable and may
create an electrical shock hazard to personnel. Such a failure or shock could result in serious
personal injury, loss of life and/or equipment damage. DC voltage sources should provide proper
isolation from main AC power and similar hazards.

PLC Port
The cable connecting PLC to OIS is attached to PLC Port. Different cables are required for different
PLCs /controllers. Cable details for any particular PLC are given in the Operation Manual for that PLC.

Serial Port
OIS60 units have two communication ports - Multi-Signal PLC Port and RS232 Serial Port. Description
of each is given in the following topics.
Serial port is used to download the firmware and application in the OIS unit. OIS also has serial printout
capabilities. This port can be attached to a computer / serial printer using the proper cable. This port is
always active. When OIS is communicating with a PC for programming, PLC operations are suspended.
Pin description of the Serial Port as seen on the OIS60 unit is given below:
