ABB | DSTD110A 57160001-TZ | Digital Output Card

Product Description:

These give short-circuit-protected static outputs for 24 V d.c. (transistor outputs). The load current may be a maximum of 150 mA per channel for DSDO 115 and 0.5A for DSDO 115A. The supply is divided in the connection unit into two groups of 16 channels each. Each has a common supply and 0V. The outputs are galvanically isolated from the internal electronics.

• Input units are available for standard voltage or current signals, single-ended or differential, with or without live zero.
• An isolation amplifier is available in the form of a connection unit. The isolation voltage is 3 kV.
• Some board has reference channels for automatic calibration and testing.
• The data base is updated by scanning, with cycle times normally selected from the range 100 ms to 600 s.
• Optional software filtering, square-root linearization and deadband limits for updating can be selected.
• Optional redundancy. Two types of boards can be duplicated to achieve increased availability.
• A board is offered which combines analog inputs and analog outputs (loop dedicated I/O).
