Non-Hazardous Area Connector CON1, Pins 1 to 6 & 9 to 12
Um = 30V
The non-hazardous Connector CON1, pins 1 to 6, & 9 to 12 are designed to operate
from a d.c. supply voltage of up to 30V supplied from either safety extra low-voltage
(SELV) or protective extra low-voltage circuits, for example equipment complying with
the requirements of either the IEC 60950 series, IEC 61010-1 or a technically equivalent
standard.
Digital O/P Configuration - Hazardous Area Terminals 4 w.r.t. 3
(IS Power Jumper Link not Fitted)
Uo = 26.5V
Io = 90mA
Po = 0.6W
Digital O/P Configuration - Hazardous Area Terminals 4 w.r.t. 3
(IS Power Jumper Link Fitted)
Uo = 26.5V
Io = 136mA
Po = 0.9W
Analogue O/P Configuration – Hazardous Area Terminals 4 w.r.t. 2
(IS Power Jumper Link not Fitted)
Uo = 26.5V
Io = 90mA
Po = 0.6W
Analogue O/P Configuration – Hazardous Area Terminals 4 w.r.t. 2
(IS Power Jumper Link Fitted)
Uo = 26.5V
Io = 136mA
Po = 0.9W
Digital I/P Configuration – Hazardous Area Terminals 2 w.r.t. 3
Uo = 10V
Io = 0.13mA
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.
