General description:

D2000M series Intrinsically Safe Multiplexing System consists of one to four

Analog-Temperature Multiplexer units model D2010M, up to twelve Expander units

model D2011M, or up to four Digital Multiplexer units model D2030M, mounted in

Hazardous Area/Hazardous Locations Zone 1-2, Gas Group IIC-IIB-IIA T4 or

Class I, Division 1-2, Group A, B, C, D T4 and connected via a single/redundant 2 wires

data communication/supply line to a Modbus Gateway unit model D2050M,

mounted in Safe Area/Non Hazardous Locations and connected to a PLC, DCS or PC.

Multiplexer D2030M units can be installed in the field, close to input sensors, for data

acquisition of signal from Hazardous Area/Hazardous Locations Zone 0-1-2 or

Class I, Class II, Class III, Division 1-2.

The units are primarily intended for Hazardous Area/Hazardous Locations acquisition of

voltage free contact or EN60947-5-6 proximity detectors.

D2030M scans all channels and stores all data in a memory buffer, where they can be

rapidly accessed by the Modbus Gateway D2050M unit.

Each D2030M unit accepts directly up to 32 input channels.

Four D2030M units achieve 128 inputs with a single Modbus Gateway D2050M unit.

Redundant communication is obtained by dual data/supply interface line.

Safety parameters mantain compatibility with Gas Group IIC or Gas Group A and B,

even in redundant mode.

All parameters are software configurable by serial commands via D2050M Gateway

unit. Functions and serial commands for RS-232 and RS-485 protocols are provided

in the instruction manual.

Features:

• Intrinsically Safe for installation in Zone 1, 2 Gas Group IIC, IIB, IIA T4

or Class I, Division 1, 2 Groups A, B, C, D, Temperature Code T4 and

Class I, Zone 1, 2 Groups IIC, IIB, IIA, Temperature Code T4

Hazardous Area/Hazardous Location.

• Inputs from voltage free contacts or EN60947-5-6 proximity detectors

from Zone 0, 1, 2 or Class I, II, III, Division 1, 2,
