15.ENVIRONMENTAL CONDITIONS: Operating Temperature Range: 0 to 50°C Storage Temperature Range: -40 to 80°C

Operating and Storage Humidity: 85% max. relative humidity (non-condensing) from 0°C to 50°C.

Altitude: Up to 2000 meters

16.SERIAL COMMUNICATIONS (Optional):

Isolation To Signal Input Common: 500 Vrms for 1 min. Working Voltage: 50 V max., CAT I

Not isolated from all other commons.

Type: Bi-directional 20 mA current loop, 20 mA source provided on transmit loop. (Powers up to 7 units in a loop with internal current source).

Baud Rate: programmable 300 to 2400

Maximum address: 99 (Actual number in a single loop is limited by serial hardware specifications.)

Data Format: 10 bit frame, Odd parity (one start bit, 7 data bits, one odd parity bit, and one stop bit.)

Serial Hardware Specifications:

SO - Output Transistor Rating: Vmax = 30 VDC, VSAT = 1Vmax at 20 mA. Note: This will allow up to 28 units maximum in each loop.

SI - Input Diode Rating: VF = 1.25 VTYP; 1.5 VMAX

Note: The compliance voltage rating of the source must be greater than the sum of the voltage drops around the loop. (Typically a 30 VDC powered source would be capable of operating between 18 and 22 units in a loop.)

17.ALARMS (Optional):

Solid State: Two, isolated, sinking open collector NPN transistors acting in parallel with relays. Imax: 100 mA. VSAT = 1.0 V @ 100 mA. Vmax: 30 VDC.

Isolation To Signal Input Common: 500 Vrms for 1 min. Working Voltage: 50 V max., CAT I

Not isolated from all other commons.

Relays:

Isolation To Signal Input Common: 2300 Vrms for 1 min. Working Voltage: 300 V max., CAT II

Type: Form C (2)

Max. Rating: 5 Amps @ 120/240 VAC or 28 VDC (resistive load), 1/8 hp @ 120 VAC (inductive load).

Relay Life Expectancy: 100,000 cycles at max. rating. (As load level decreases, life expectancy increases.)

18.ANALOG OUTPUT (Optional): Digital scaling and offsetting Isolation To Signal Input Common: 500 Vrms for 1 min.

Working Voltage: 50 V max., CAT I

Not isolated from all other commons.

4 to 20 mA:

Compliance Voltage: 10 VDC (500 ￿ max. loop resistance)

0 to 10 VDC:

Accuracy: ±(0.1% of reading + 35 mV)

Resolution: 12 bits

Min. Load Resistance: 10 K￿ (1 mA max.)

19. PEAK/VALLEY/SLOPE/OFFSET (Optional):

Peak and Valley recording. Programmable temperature offset and slope.
