ABB PFSK162 3BSE015088R1 Regional controller module

MService targets two main application scenarios:

 Customer’s staff can use the device for performance analysis and continuous support of

maintenance planning for MNS and MNS iS system, with MService installed as permanent part of the switchgear.

 ABB’s service personnel uses the device to place it in a customer’s switchgear to

support customer decisions in keeping the switchgear in good condition by collecting

data for a certain time and derive an assessment on the switchgear performance and operational status.

To fit to these scenarios, the MService employs a small-scale, compact approach to enable fast

commissioning and ease of use.

This module has 16 digital outputs. The output voltage range is 10 to

30 volt and the maximum continuous output current is 0.5 A. The

outputs are protected against short circuits, over voltage and over

temperature. The outputs are divided into two individualy isolated

groups with eight output channels and one voltage supervision

input in each group. Each output channel consists of a short circuit

and over temperature protected high side driver, EMC protection

components, inductive load suppression, output state indication

LED and optical isolation barrier.

The process voltage supervision input give channel error signals if

the voltage disappears. The error signal can be read through the

ModuleBus. The outputs are current limited and protected against

over temperature. If the outputs are overloaded the output current

wi l be limited.

The AI835/AI835A provides 8 differential input channels for

Thermocouple/mV measurements. Measurement ranges configurable

per channel are: -30 mV to +75 mV linear, or TC Types B, C, E, J, K, N, R,

S and T, for AI835A also D, L and U.

One of the channels (Channel 8) may be configured for “Cold

Junction” (ambient) temperature measurements, thus serving as CJ

channel for Ch. 1 .7. The junction temperature may be measured

loca ly on the MTUs screw terminals, or on a connection unit distant

form the device.
