・
Sensor is a thermocouples, RTD’s, passive resistive switch devices, or is CSA entity
approved and meet connection requirements.
・
Electrical data of the SC202S.
- Supply and output circuit (ter and -)
Maximum input voltage Vmax = 31.5 V. Maximum input current Imax = 100 mA.
Maximum input power Pmax = 1.2 W.
Effective internal capacitance Ci = 22 nF. Effective internal inductance Li = 35
P
H.
- Sensor input circuit (terminals 11 through 16):
Maximum output voltage Voc = 14.4 V. Maximum output current Isc = 13 mA.
Maximum allowed external capacitance Ca = 59 nF.
Maximum allowed external inductance La = 200 mH.
・
Barriers and power supply should be CSA certified. The specifications must not exceed
the maximum values as shown in the diagram above. Installation should be in
accordance with Canadian Electrical Code, Part I.
Maximum safe area voltage should not exceed 250 VRMS.
For Class I, Div. 2, Group ABCD the CSA certified barrier is not required, and the Sensor
input circuit (terminals 11 through 16) is non-incendive having the parameters :
Maximum output voltage Voc = 14.4 V. Maximum output current Isc = 13 mA.
Maximum allowed external capacitance Ca = 2.9
P
F.
Maximum allowed external inductance La = 450 mH.
・
The Hand Held Communicator must be of a CSA certified intrinsically safe type in case
it is used on the intrinsically safe circuit in the hazardous area, or of a CSA certified
non-incendive type in case it is used on the non-incendive circuit in the hazardous area.
