analog inputs and all outputs except for the Second Current
Output.
On contact closure the controller will respond according to how
each digital input is configured. Opening the contact causes a
return to previous state.
The second Digital Input is mutually exclusive with the Second
Current Output.

Types
Electromechanical Relays (One or Two)
Single-Pole Double-Throw (SPDT) contacts. Both Normally Open
and Normally Closed contacts are brought out to the rear
terminals. Internally socketed
l
Resistive Load: 5 amps @ 125 Vac, 250 Vac or 30 Vdc
l
General use: 5 amps @ 125 Vac, 250 Vac (certified by UL)
l
Inductive Load (cosφ = 0.4): 3 amps @ 130 Vac or 250 Vac
l
Motor: 1/6 H.P 125 Vac, 250 Vac.
Dual Electromechanical Relays
Two Single-Pole Single-Throw (SPST) relays. One Normally Closed
contact for each relay is brought out to the rear terminals. This
option takes the place of one of the above electromechanical
relays, and is especially useful for Time Duplex or Three Position
Step Control or Position Proportional Control applications.
Instruments with this option can have a total of 4 relays plus one
current output. Internally socketed
l
Resistive Load: 2 amps @ 125 Vac, 250 Vac or 30 Vdc
l
General use: 5 amps @ 125 Vac, 250 Vac (certified by UL)
l
Inductive Load (cosφ = 0.4): 1 amps @ 130 Vac or 250 Vac
Open Collector Outputs (One or Two)
Socketed assembly replacing a relay. Two types of load are
supported, resistive load and pilot duty load. Opto-isolated from all
other circuits except current output and not from each other.
Internally powered @ 28 Vdc (0 mA) ~ 24 Vdc (20 mA).
NOTE: Applying an external power supply to this output will
