cal23dt-hv

• Voltage or current input:
0..50 mV (+/-50 mV) to 0…3000 V (+/- 3000 V)
0…1mA (±1mA) to 0…10A (±10A)
• High galvanic isolation, dielectric strength 5kV AC / 7kV DC
• Voltage output 0..10V (±10V)
• Fast signals, bandwidth up to 30kHz
• Applications: Energy, rail

The CAL23DT-HV is a transmitter designed for voltage measurement on equipment
that may be exposed to high voltages (power distribution, railways, transformers, motors,
alternators, etc.) and requires maximum safety.

Isolation amplifier providing protective galvanic isolation for high-voltage common-mode measurements.
These devices are designed for monitoring electrical systems operating at voltages up to 1000 VDC

4-20mA SIL3 / SIL2 CURRENT LOOP ISOLATOR DUPLICATOR

cal23dma

• Current inputs: (0…4.20 mA) With or without sensor power supply
• Simulation port: (automatic input switching) Allows for complete loop verification without disconnection
• Quadruple galvanic isolation (1000 V)

• 2 Independent Active or Passive Current Outputs; Impedance: 750 ohms

• Fully analog design
• Plug-in connectors
• Universal power supply: 20 to 265 VAC/VDC or 24 VDC
• HART transparency
• SIL2 and SIL3 compliance according to IEC 61508
The CAL23DmA-S2 analog signal converter provides isolation and duplication of 4..20mA
with a very high level of reliability. The quadruple galvanic isolation (Input/ Output 1/ Output 2/ Power Supply)
allows for complete independence of the current loops.
