MDJ874 Solid State Timer
Description:
The MDJ874 series of solid state time delay switches are designed to be direct replacements for the following obsolete models, used in the CANDU nuclear power plants.
| Current | Obsolete | |
|---|---|---|
| Lisle-Metrix | Lisle-Metrix | Agastat |
| MDJ874A | MD/LR-TDE | 9111 |
| MDJ874B | MD/LR-TDD | 9110 |
| MDJ874C | MD/LR-TDR | 9112 |
The MDJ874 timers are designed with solid state circuitry. The timer is based on a sixteen stage configurable binary counter, with an integral oscillator controlled by an external RC network. The output is a power transistor, which energizes the output at 48Vdc with a maximum current supply of 1 amp.
The timers are housed in a black ABS enclosure with an 8 pin octal plug. The plug is keyed to ensure proper alignment with the mounting base. The timer is secured to the base with a built in bracket and two mounting screws.
