2-9 Installation & Wiring
Output Wiring (cont’d)
• Analog output modules source the analog signal.
• No external supply is required.
• Analog output signals are isolated.
DC Output
AC Output
Sourcing
• When other switching devices are in series or parallel with the AC output
module, connect a varistor (MOV) across the terminals to prevent
module damage from inductive voltage spikes.
• Output modules act like switches; they do not supply power to loads.
Analog Output
• Suppress spikes in inductive DC loads with one of the following
methods:
Connect a zener diode across the terminals. Turn off time will not be
significantly affected. Voltage rating of diode must be greater than the
normal circuit voltage. 50 VDC Zener, #EC-9001-5369; 200 VDC
Zener, #EC-9001-5388.
Connect a reverse-biased diode across the load. This will increase the
turn off time of the load. #EC-9001-4004.
