Terminal Description
TB1
RJ45 connector which is hardware configured
to either RS485 or RS232, or a 3 way terminal
block for RS485.
TB2
Voltage and current inputs.
TB3
I/O - PI3 or PO3.
TB5
I/O - PI4 or PO4.
TB6
I/O - PI5 or PO5.
TB8
I/O - PI6 or PO6.
TB9
RJ45 connector which is hardware configured
to RS232 or RS485.

Table 2-3 Mk10A Terminal block connections
All 4 I/O can be either SØ Outputs, BOSFET Outputs or 240V/110V/48V/12V/5V
Inputs. PO3 and PO6 have the option of a 2A, 240V relay. TB5 and TB6 should not be
considered as isolated from each other (1mm creepage between them). Isolation of TB1
to TB3, TB3 to TB5 and TB6 to TB8 is 4kV (unless active inputs are fitted, in which
case there is no isolation between TB1 and the active inputs). All I/O are isolated from
the line (neutral) by 4kV.
UPS Variant
The UPS variant offers UPS backup, and separates the LED from the I/O. Only Active
inputs are available though. Figure 2-9 shows the terminal layout, and Table 2-2 lists the
terminal block connections.
