RELAY OUTPUTS:
Relay Contacts: Isolated Form C (SP/DT)
Rated at 3 amps 120 VAC, via 3 pigtail leads
(6" long nom for Model CM),
or 3 position Barrier strip for all other Modules.
LOGIC LEVEL OUTPUTS:
Pull up resistor (3K) to + 5 VDC) When there is No CONDENSATION (or SENSOR FAULT) condition, output = nom. 5 VDC. When there is a CONDENSATION (or SENSOR FAULT) condition, output = < 0.4 VDC
OPEN COLLECTOR OUTPUTS: Solid State equivalent of "Voltage Free Contacts".
Max. voltage across output transistor with No CONDENSATION (or SENSOR FAULT) condition = 30 VDC. Max. current through transistor when there is a CONDENSATION (or SENSOR FAULT) condition = 100mA.
POWER IN:
For Relay Modules, nom. 12 VDC or VAC via a "concentric" (2.5 mm x 5.5 mm) power jack.
A mating plug is provided unless the Model PM-A Power Module is ordered.
Draws Nom. 20 mA de-energized; to approx. 200 mA energized (with 2 relays energized).
POWER SUPPLY:
An optional plug-in "Model PM-A" power module is available. It supplies 12 VDC to its mating concentric power plug from a 120 VAC (US style) wall receptacle ("wall wart").
SIZE:
For relay modules; Nom. 5.0" (12.7cm) x 2.7" (6.7 cm) x 0.9" (2.3 cm) - except for Model ICM - R1 (or -R2) which is 2.0" (5.8 cm) High. Distance between all module mounting holes - 4.5" (11.5 cm).
TEST:
Each Module has a form of circuit TEST. All Modules except the Model CM, incorporate a unique "SENSOR FAULT" test feature as a separate output and indication. Note: Relay Modules with this SENSOR FAULT feature "Latch" the this output when it occurs. It must be "RESET" (Button) after problem is attended to.
Operating Enviroment:
All circuit boards are conformally coated to resist moisture.
Operating Temperature: 0*C to 65*C (80*C on special order)
Alternate Configurations:
We are very applications oriented and will consider other configurations to suit
special applications
