Input

Current: DC-currents up to 20 mA, input impedance

ca. 100 Ohm. Overvoltage protection up to 30 V (self

resetting PTC-fuse). Surge/burst protection up to 3

kV.

Voltage: Range 1: 0-400 mV, input impedance ca.

100 MOhm; range 2: 0-10 V, input impedance 250

kOhm. Upon request up to 60 VDC, also negative

voltages. Overvoltage protection up to 30 V (self

resetting PTC-fuse). Surge/burst protection up to 3

kV.

Relays:

Relays with gold plated , switching uV/uA as well as

2A/250VAC. Test voltage: 1000 V

Operating Modes

•

One or two independent limiting values

(thresholds, relays 1 and 2)

•

Window comparator (only relay 1)

•

Two-position controller (only relay 1)

The operating mode is selected by DIL-switches.

Supply

All

modules

are

suited

for

unregulated,

noisy

industrial power supplies; nominal value is 24 VDC

(min. 20V, max. 30V). Other supply voltages on

request. Option: isolated power supply.

Operating modes/Settings

•

Input: 0-400 mV, 0-10 V, 0-20 mA: DIL-Switch

•

Relay inversion switching status: DIL-Switch

•

Hysteresis (0.1-2 %): trimming potentiometer

•

Time delay (0.05 - 1 sec., only for relay 1):

trimming potentiometer (option)

Options

•

DC-DC-converter for power supply (0.7 or 3 kV

test voltage)

•

Second relay (only for „high“ limiting value)

•

Time delays (only for relay 1). Adustable input

filter.

•

Open input detection, current interruption (4-20

mA) detection. Such a condition will switch the

relays off (safe status, independent of operating

condition).
