B.2.11 Modules With HART® Protocol
The HART® protocol (Highway-Addressable Remote Transducer) is a communications protocol over a direct current loop
(0-20 or 4-20mA). This protocol is used to without interfering with current measurement to both read measurements
carried out by the HART® transmitter and transmitter
The CALYS 1500 with related HART® module (ACL500) is used to carry out all of these operations.
To use the CALYS 1500 in HART mode, the unit must be connected to the current loop (across 24
channel V1) and be provided with the specific ACL500 modem (connected to the unit's side).
The calibrator provides the loop power supply via an internal 250
When an external loop power supply is used, a resistor from 230
