[26 - 20 AWG]
Isolation
Relay connections are isolated to 250V dc from all
other circuitry, earth and system common.
Digital Outputs
Number of Digital Outputs/Relays
3 (shared with Digital Inputs 1, 2 & 3)
Connection Arrangement
Open drain with weak 47k internal pull-up to 5V,
referenced to BUS +ve (chassis)
Connectors
Screwless terminal blocks
Wire Size
0.2 – 0.5mm

[26 - 20 AWG]
Isolation
Relay connections are isolated to 250V dc from all
other circuitry, earth and system common.
Digital Inputs
Number of Digital Inputs
5 (shared with Digital Outputs 1, 2 & 3 and Analog
Inputs 4 & 5)
Connection Arrangement
Digital Inputs 1, 2 & 3 expect an open drain, open
collector, relay or mechanical switch contact to
BUS +ve (chassis). A weak 47k internal pull-up
resistor to 5V is provided. Inputs are referenced to
BUS +ve (chassis).
Digital Inputs 4 & 5 expect an open drain, open
collector, relay or mechanical switch contact to
BUS +ve (chassis). An external pull-up to 3V3 or
5V is required. Inputs are referenced to BUS +ve
(chassis).
Connectors
Screwless terminal blocks
Wire Size
0.2 – 0.5mm
2
[26 - 20 AWG]
Input Range
0V which is BUS +ve (chassis)
To
10V above BUS +ve (chassis)
Input Common
Bus +ve
Input Protection
Protected against damage from short circuit to bus
+ve or bus -ve
Analog Inputs
Number of Analog Inputs
2 (shared with Digital Inputs 4 & 5)
Connection Arrangement
Analog Inputs 4 & 5 expect an input voltage
referenced to BUS +ve (chassis). For midpoint
monitoring this will be –ve and half the string
voltage. For the 10V range this will be +ve and up
to 10V above BUS +ve.
Connectors
Screwless terminal blocks
