2.13.1 Insulation Amplifier PXUB 201
Insulation amplifier PXUB 201 is used when galvanic insulation between input and output, or
between power supply and input/output, is required. See Section A.6.1 Insulation Amplifier
PXUB 201.
Insulation amplifier PXUB 201 is intended for installation on a DIN-rail. The PXUB 201 is
connected by screw terminals.
PXUB 201 is normally supplied from the same +24 V DC supply that supplies the tension
electronics.
If PXUB 201 is mounted close to the terminal group, it is not necessary to use a screened cable
between the tension electronics and PXUB 201.

2.13.2 Relay Board PXKB 201
The digital outputs on PFEA113 are isolated as a group and should not be connected to more
than 24 V DC. In the following applications should relays be connected to the digital outputs:
• The digital outputs must be isolated from each other.
• The signal to the superior system is higher than 24 V DC or an AC signal.
The PXKB 201 is intended for mounting on a DIN-rail.
