Red Lion LEGEND - Manual (Page 48)

SPECIFICATIONS
1. DISPLAY: 2x8, 0.3" (7 mm) high characters, negative image transmissive
LCD, with yellow/green or red LED backlighting.
2. POWER:
AC Operation: 115/230 VAC ±10%, 50/60 Hz,
10 VA, switch selectable.
DC Operation: +12 VDC ±20% @ 250 mA.
3. MEMORY: Non volatile memory retains all programming information.
Count and Preset values are written to non volatile memory when power is
interrupted. All other programming parameters are written to memory when
programming mode is exited. If power is removed while in the programming
menus, the parameters are restored to previously saved settings.
4. SENSOR POWER: +12 VDC ±25% @ 100 mA.
5. INPUTS A and B: DIP Switch selectable to accept count pulses from a
variety of sources including switch contacts, outputs from CMOS or TTL
circuits, and all standard RLC sensors.
