Ask on WhatsAppRotor voltage speed feedback module and the RS232 to RS485 modem sets used with the ABB ASTAT crane motion controller.
Legacy product line, discontinued by the manufacturer. Supplied as a sourced spare on request. ABB's stated modern equivalent is the ACS880 drive with the Crane Control program (option +N5050).
The DADT 100 measures rotor frequency straight from the motor slip rings, which lets the ABB ASTAT system run closed-loop speed control without a tachometer or pulse encoder on the motor shaft.
It also provides rotor monitoring. The DADT 114 and DADT 124 are a matched modem pair that converts the ASTAT RS232 service port to an RS485 multi-drop link, so a single service PC can reach up to 254 units on one crane or in one bay.
