HYDRAN 201CI-C continuous on-lineIntelligent Transmitter

Standard Analog OutputNon-isolated, jumper-configurable as 0-1 mAor 4-20 mA (10 V max. output), 0-l V or0-10 V; 0-2000 ppm scale
2nd Optional Analog OutputIsolated, jumper-configurable as 0-l mA4-20 mA, 0-1 V or 0-10 V; 1500 V RMSisolation level; 0-2000 ppm scale
Gas Hi and Hi-Hi Alarms
Duplicate alarms in the H201Ti for Level.Hourly Gas Trend and Daily Gas Trend
Fail Alarm
Duplicates alarm in the H201Ti for powerfailure, loss of communications, sensor orother system malfunctions; upon systemfault, display is blanked and analog outputs
are set to zero
Alarm ContactsGas Hi, Gas Hi-Hi, Fail SPDT (type C), 125 VA@ 250 Vac, 60 w @ 220 Vdc
Gas Alarm IndicatorsHi and Hi-Hi illuminated pushbuttons mountedon door; latched on when alarm is triggered.turned off by pressing button as alarm is cleared

RS-232 Local PortStandard RS-232 port (DB-9) allows serialcommunications with a local computer(or remote computer with optional smartmodem); any H201Ti can be accessedthrough any H201Ci Controller
Supervisory Link Power SupplyA separate isolated dc power supply provides+l5 V (impedance protected) for the opto-isolated supervisory link
RecommendationRun all communication cables in flexibleor rigid metallic conduits for maximummechanical and electrical protection
