to either RS485 or RS232, or a 5 way terminal
block for RS485.
TB2 Voltage and current inputs.
TB3 I/O - PI5 or PO5.
TB4 I/O - PI6 or PO6.

• Table 2-1 Terminal block connections
Outputs are BOSFETs, up to 240V, 100mA, AC or DC. Inputs are AC or DC in a
range of voltage options. An active input option is not offered on this variant. All I/O’s
are isolated from each other to 2kV, except for active inputs which share a supply with
the modem port. All I/O are isolated from the line (neutral) and TB1 by 4kV.
Special I/O Variant
This variant separates the LED’s from the I/O, and provides more I/O type options.
Figure 2-7 shows the terminal layout, and Table 2-2 lists the terminal block connections.
