Hitachi LYD105A 8-Channel Digital Output (DO) Module

Hitachi LYD105A 8-Channel Digital Output (DO) Module

LYD105A is an 8-channel digital output (DO) module for Hitachi H-5000M/LY series DCS systems, used with corresponding terminal boards.
The core function of LYD105A is to receive logic instructions issued by the main control CPU, output 24V DC switch signals after photoelectric isolation and power drive, and use them to drive loads such as field relays, solenoid valves, sound and light alarm indicators, valve actuators, etc; LYD105A is equipped with channel short circuit and overload fault detection, and can feedback the output circuit status back to the control system. It is an execution output card for unit interlocking, equipment start stop, and alarm output circuits.

Product features

1. 8-channel source type DC output, with a maximum of 0.5A per channel, suitable for driving conventional on-site loads such as 24V solenoid valves and intermediate relays.
2. Optoelectronic grouping isolation design isolates on-site load side interference to prevent external faults from entering the backplane bus and damaging the main control.
3. Each channel has independent short circuit and overheating protection, and a single channel failure will not cause the entire card to burn out, resulting in better fault tolerance.
4. The switch response speed is fast, up to 0.3ms, meeting the requirements of fast action timing for interlocking circuits.
5.  Equipped with TD105A terminal board, centralized wiring, convenient for on-site wiring, maintenance, and replacement.
6. The board is coated with three anti coatings to prevent moisture and dust, and is suitable for high dust and strong electromagnetic interference control cabinet environments such as power plants and chemicals.
7.  The panel comes with power, operation, and channel fault indicator lights, which provide intuitive fault location and shorten troubleshooting time.
8. The backplane bus is natively compatible with Hitachi LY series CPU, AI, DI, and AO modules, with simple configuration.
9. In the off state, the leakage current is extremely low to avoid accidental triggering of small loads
10.  Belonging to discontinued spare parts, a large number of old Hitachi H-5000M DCS devices are in use, which are commonly used maintenance replacement cards.
