Digital I/P Configuration – Hazardous Area Terminals 1 w.r.t. 2
Uo = 10V Ci = 0.5nF
Io = 14mA Li = 0
Po = 35mW
Analogue I/P Configuration – Hazardous Area Terminals 2 w.r.t. 3
Uo = 10V Ci = 0.5nF
Io = 0.13mA Li = 0
Po = <1mW
The hazardous area terminals 2 w.r.t. 3 are also considered suitable for the connection
of an external intrinsically safe source with a Uo = 30V and Io = 100mA. When an
intrinsically safe source is connected to these terminals the capacitance and either the
inductance or inductance to resistance ratio (L/R) of the hazardous area connections
must not exceed the values detailed in the certificate of the intrinsically safe source.
Hazardous area terminals 1 & 4 must not be used when a source is connected to these
terminals.
Analogue I/P Configuration – Hazardous Area Terminals 4 w.r.t 2
(IS Power Jumper Link not Fitted)
Uo = 26.5V Ci = 0.5nF
Io = 90mA Li = 0
Po = 0.6W
Analogue I/P Configuration – Hazardous Area Terminals 4 w.r.t 2
(IS Power Jumper Link Fitted)
Uo = 26.5V Ci = 0.5nF
Io = 136mA Li = 0
Po = 0.9W
Analogue I/P Configuration – Hazardous Area Terminals 2 & 4 w.r.t 3
(IS Power Jumper Link not Fitted)
Uo = 26.5V Ci = 0.5nF
Io = 90mA Li = 0
Po = 0.6W
Analogue I/P Configuration – Hazardous Area Terminals 2 & 4 w.r.t 3
