Type	Input	Relays	Power Supply
COM 90-1	progr.	1	20-30V
COM 90-2	progr.	1+2	20-30V

Input:

• Programmable via DIL-switches: 0-20 mA/100 Ohm input impedance, 0-400 mV/100 MOhm input impedance 0-10 V/250 kOhm input impedance.

Relays:

• 250 VAC/2 A max. switching voltage/switching current, max. 24 W/60 VA switching capacity, test voltage 1000 VAC. Gold-plated relay contacts also for µV/µA-signals.

Power Supply:

• Max. current requirement with two relays is 80 mA.

Operating Mode:

• The operating mode is selected via DIL-switches:
  1. One or two (relays 1 and 2) independent limiting values (thresholds).
  2. Window comparator (only relay 1).
  3. Two position controller (only relay 1).
• Additional settings: relay inversion switching status, hysteresis (0.1-2% by trimming potentiometer).

Options:

• Second relay (only for "high" limit)
• Open input detection/current interruption (relay released)
• Time delays (fixed or programmable)

When ordering, please specify:

• COM 90-1 or -2 (with two relays)
• DC-DC converter for the power supply
• Basic version: COM 90-1 (with one relay), no DC-DC converter, no time delay
