SIZE In accordance with type 170 Specifications
POWER REQUIREMENTS 89 to 135 volts ac, or as per applicable specification.
60 +/- 3 Hertz 1 Amp SLO-BLO fusing
TEMPERATURE -34°C to +74°C Operating       -50°C to +85°C Storage
CHANNELS MONITORED 16 Channels, 18 optional - add "-18" to model number.
Controller Watch Dog, 1.0 seconds or 1.5 seconds. 48 ac field wire voltages (54 as an option, "-18")
DISPLAYED INFO All active channels, power, and FAULTS on LEDs. Most recently recorded FAULT including signal status automatically displayed on front panel LEDs.
RESET `RESET' button prevents defeating unit operation
BASIC FUNCTIONS Conflicting Green or Yellow on any two or more non-compatible channels (full or half-wave). Failure of Watch Dog Timer signal (Watch Dog Error). Low DC power input (24VDC).
ENHANCED FUNCTIONS Short Yellow selectable by channel. Sequence monitoring selectable for each channel. No Input (Absence of Red) selectable by channel. Multiple Output selectable for each channel. Selections made using DIP switches. Low (Brownout) and high AC line voltage. Failure due to removal of program card.

Meets CALTRANS TYPE 170 requirements. Performs RMS (not peak) and out of phase voltage monitoring for Green, Yellow and Red inputs. Supplied with Model 210-DC Diode program card for programming permissives and Yellow inhibit. Uses internal Menu-driven Set-up Program and DIP switches for making monitoring selections by channel.
