Application
The SDR-32 provides lamp drivers for LED or incandescent lamp
annunciators. The high circuit density makes the SDR-32 module ideal
for driving graphic annunciators.

Installation
The SDR-32(K) may be installed in the SAN-4, SAN-8, or RSAN-6
enclosures. For integral mounting within a custom annunciator
enclosure, the card only version (without mounting plate) may be
ordered.
The SDR-32(K) module requires four groups of 8 output addresses of
the SAN-CPU to which it is connected.
Jumper Setup
JP1
Install JP1 if the SDR-32(K) is the last module installed on the
data line.
Field Wiring
Plug the ribbon cable assembly (P/N 250080) from the previous SAN
series module into P2 and plug the ribbon cable into P1 on the next
SAN series module. Connectors PO1 through PO4 mate with pigtail
cable assemblies which connect to the individual lamps. The Negative
(-) side of the lamp power supply must be connected to the (-) SAN-
CPU terminal.
Caution:
When using incandescent lamps, some current limiting is
advised as momentary current surges can exceed 100mA rating on the
switching transistor causing permanent damage.
