Scientech - OCA801 - One Channel Isolator Brochure

NUSI 800 Series One Channel Isolator Scientech NUSI Products are manufactured by Scientech, C16 a business unit of Curtiss-Wright Flow Control Company.  The OCA801 One Channel Isolator replaces the obsolete Hagan 7100 single channel isolator, and has the following functions: ? Electrically isolates an input signal from faults at the output or on the power line, to prevent output-side problems from affecting safety-related inputs. ? Acts as a signal buffer (repeater) that enables more connections to the output. ? Performs voltage-to-current signal conversion.   OCA801 OCA800 OCA801 SPECIFICATIONS Power Supply Voltage:  120 V ac RMS ( ± 10 %), 60 Hz ( ± 5 %) Power Consumption:  2 W typical, 3 W, 50 VA maximum inrush Accuracy:  ± 0.1 % of output full scale, repeatable to 0.05 % Linearity:  Better than ± 0.05 % of output full scale Dielectric Withstand:  3000 V dc and 1000 V ac (RMS) from input to output     1000 V dc and 1000 V ac (RMS) from input to case Credible Live Fault:  480 V ac, 140 V dc at 20 A Surge Withstand:  Using the waveform described in IEEE-472-1974 Temperature Effects:  Less than 0.50 % change of output full scale per 50 °F change in temperature for overall module gains less than 1.7; otherwise, less than 0.05 % of output full scale change for 1 °C change in temperature Electrical Qualification:  Plant protection, qualified to IEEE 323-1974/1983 and IEEE 344-1975/1987 Ambient Temperature:  35 °F to 122 °F (2 °C to 50 °C) (normal operation)   122 °F to 135 °F (50 °C to 57 °C) (abnormal operation for 200 hours)   -40 °F to 185 °F (-40 °C to 85°C) (storage) Relative Humidity:  0% RH to 95 % RH, non-condensing Pressure:  Atmospheric Radiation Limits:  104 rad TID gamma over forty yearsNUSI 800 Series One Channel Isolator Scientech 208.524.9200 fax: 208.524.9238 www.scientech.cwfc.com C17  HOW TO ORDER  The model number and configuration typically should be specified as follows: Example: OCA801-05-07-08  POWER SOURCE:See table 3OUTPUT RANGE:See table 2OCA80xINPUT RANGE:See table 1C2 C3- -C1 -   Table 1 – Input Range Table 2 – Output Range Code Input Range Impedance ?
