Controls:............................Four push buttons, user’s selections are stored in EEPROM.
Outputs:............................. Analog
: voltage by order or current user selectable 4-20mA or 0/24mA. Linear to the selected engi-
neering units, the range is programmable. Output resolution is 0.1°C dewpoint, linearity 1%, max load
resistance 500 Ohms.
Digital
RS-232C (9600,8,E,1), can interface to a Personal Computer or other RS-232 device.
Alarm relay contacts:........Ordinary use, explosion-proof housed, and safe area instruments: 10A, 250VAC or 30VDC.
Intrinsically Safe Div 2 instruments use hermetically sealed relays: 3A, 120VAC
Isolation: ...........................Sensor is isolated from power ground, analog output and RS-232, but they are shunted with a 33V tran-
sorb, a 1M Ohm resistor and 0.1uF capacitor. Refer to Electrical Connections section.
Approvals/Classifications: CE for electromagnetic compatibility, accredited laboratory tested and certified
UL and cUL for ordinary field wired use
Intrinsically Safe configurations: for NEC standard IS installations UL,
for CENELEC standard IS installations DEMKO,
refer to instrument labeling
