Trip output and binary input unit 216DB61

– 8 outputs for bipolar control of auxiliary trip relays

– Monitor Output Amplifier

– 16 digital inputs for signaling auxiliary relay assemblies 

(each two can be used separately to externally enable and prevent tripping)

– Activated outputs and inputs are indicated by LEDs

– Front space requirement: one rack partition.

Auxiliary DC power supply units 216NG61. 216NG62 and 216NG63

– Models for 36 to 312 VDC inputs

– Output 24 VDC, 150 watts

– Short circuit and overload protected outputs

– Parallel connection for higher ratings

– Parallel connection for redundancy (2 outputs)

– Space required: 3 rack partitions.

All protection functions of the REG216 operate on sampled primary system voltage and current.

The analog input unit has a sampling rate of 12 times per cycle and

a dynamic range of 15 bits at the rated power system frequency.

All further signal processing is performed digitally.

As a result, the protection functions are universally applicable, highly accurate and have excellent long-term stability.

Digital filters effectively suppress DC components and harmonics to avoid interference.

The trip logic of the internal protection functions (earlier diode matrix) is controlled by software in the REG216.
