Digital Output Unit 216AB61

– 32 outputs for controlling relays that output auxiliary relay assemblies

– Short-circuit proof

– Front panel LEDs to indicate activated relays

– Space required: 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.
