D1021 - SIL 2 Powered Isolating Driver with Fault Detection Smart-Hart compatible G.M. International ISM0022-6

General Description: The single channel DIN Rail Isolating Driver D1021S isolates and transfers a 4-20 mA signal from a controller located in

Safe Area to a load of up to 750  in Hazardous Area. It has a high output capacity of 15 V at 20 mA combined with a low drop across its input
terminals. The circuit allows bi-directional communication signals, for Smart I/P. In the 4-20 mA input range, a field open / short circuit (load or wire
fault) reflects a high impedance to the control device output circuit and actuates (de-energizes) the fault indication relay / transistor.
An output underrange or overrange (< 1 mA or > 25 mA) also de-energizes the fault indication relay / transistor.

Function: 1 channel I.S. mA analog output for 2 wire I/P Smart converters or valve positioners, provides 3 port isolation (input/output/supply).
Signalling LEDs: Power supply indication (green), fault condition (red).
Smart Communication Frequency Band: 0.5 to 40 KHz within 3 dB (Hart and higher frequency protocols).
EMC: Fully compliant with CE marking applicable requirements.

Supply: 24 Vdc nom (20 to 30 Vdc) reverse polarity protected, ripple within voltage limits  5 Vpp.

Current consumption @ 24 V: 70 mA with 20 mA output typical.
Power dissipation: 1.5 W with 24 V supply voltage and 20 mA output typical.
Max. power consumption: at 30 V supply voltage and overload condition 2.2 W.

Isolation (Test Voltage): I.S. Out/In 1.5 KV; I.S. Out/Supply 1.5 KV; I.S. Out/Fault Out 1.5 KV;

Input: 4 to 20 mA with  2.0 V voltage drop, reverse polarity protected.
Output: 4 to 20 mA, on max.750  load, current limited at  24 mA.

Response time: 50 ms (10 to 90 % step change).
Output ripple:  20 mVrms on 250  communication load on 0.5 to 40 KHz band.
Frequency response: 0.5 to 40 KHz bidirectional within 3 dB (Hart and higher frequency protocols).

Fault detection:

Open output detection: load resistance > 50 K.
Fault signalling: voltage free NE SPST optocoupled open-collector transistor and voltage free NE SPST relay contact (each output is

de-energized in fault condition).

Open-collector rating: 100 mA at 35 V ( 1 V voltage drop).
Leakage current:  50 µA at 35 V.
Relay contact rating: 2 A 250 Vac 500 VA, 2 A 250 Vdc 80 W (resistive load).
