Multiport Pin Details
CAUTION
All wiring to the Multiport terminal block signal lines must be rated to 30V/200mA. The +24V and GND
pins must be rated for at least 50V/5A. Temperature rating of all wiring should be greater than 70C. The
Multiport terminal block is rated for 16-28 AWG solid or stranded wire.

Name
Voltage Range
Notes
+24V
18V to 28V
Power connection must be a low impedance source.
Current ramp rate can be as much as 4A in 25µs.
GND
Earth Ground
When powering the unit through the multiport, at
least one GND pin should be connected to Earth
Ground through a low impedance path.
CH X Analog
0V to 5V
Controls the intensity of the LED channels.
CH X Digital
0V to 24V
(3.3V TTL, 24V Max)
Pin is pulled up internally; a contact closure can be
used to create a low signal. <0.5V = Low
Fault
Open Collector
(24V Max)
Active Low: Signal will be pulled low (GND) when a
fault exists.
+5V Ref
5V Output Reference
Voltage rail can be used to power potentiometers for
analog inputs.
RS232 RX
-30V to +30V
Data input to the device.
RS232 TX
-5V to +5V
Data output from the device.
