Non-IS SIL 2 Powered Isolating Driver Hart


The single channel Isolating Driver, D6020S is a high integrity analog output interface suitable for applications requiring SIL 2 level (according to IEC 61508) in safety related systems for high risk industries.
It isolates and transfers a 4-20 mA signal from a controller to a load up to 700 Ω. 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 Hart positioner.
In the 4-20 mA input range, a field open or short circuit, reflects a high impedance to the control device circuit and actuates (de-energizes) the channel Fault output transistor and actuates (energizes) the cumulative Fault output available on Power Bus connector.
Fault output signal for each channel is available when mounted on customized Termination Board. In addition the single channel D6020S provides open collector transistor output on terminal blocks. Short circuit fault detection can be enabled (two different levels can be selected) or disabled via DIP-Switch programming.
Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards.
