Page 9: Output/Power Connections
Earth ground is normally applied at the loop power supply minus terminal. Each 2-wire transmitter output varies off this ground by the voltage drop in the load resistance and lead-wire of the loop. Acromag, Inc. Tel: 248-295-0880 - 9 - - 9 - https://www.acromag.com... - Page 10 Other receivers that do not provide loop excitation are referred to as “sinking” inputs, and these will require that a separate power supply connect within the loop. These types of receivers are depicted in the figures on the next two pages Acromag, Inc. Tel: 248-295-0880 - 10 - - 10 - https://www.acromag.com...
- Page 11 (such as an I/P current-to-pressure transducer), this may reduce output stability. In this case, place a 0.1uF capacitor directly across the inductive load(s) and this will typically cure the problem. Acromag, Inc. Tel: 248-295-0880 - 11 - - 11 - https://www.acromag.com...

Respect the traditional position of earth ground in a two-wire current loop and avoid inadvertent connections to earth ground at other points in the same loop, which would drive ground loops and negatively affect operation. Acromag, Inc. Tel: 248-295-0880 - 12 - - 12 - https://www.acromag.com... -

Thus, it is highly recommended that a non- functioning transmitter be returned to Acromag for repair or replacement. Acromag has automated test equipment that thoroughly checks and calibrates the performance of each transmitter, and can restore firmware. Please refer to the Acromag Service Policy and Warranty Bulletins, or contact Acromag for complete details on how to obtain repair or replacement. -

An optional external sensor is required to monitor AC current signals for driving TB1 of the SP236 (see Acromag Model 5020-350). This toroidal sensor generates 0 to 11.17mA DC to drive the DC current input of this module with AC input current through its primary (see Table 2 of page for scaling the AC current by number of primary turns). - Page 35 22265 to 43271 or 1/21006 0-150V DC (TB2) 5.36K/1003.36K 32768 to 53774 or 1/21006 0 to 75V DC (TB2) 5.36K/1003.36K 32768 to 43271 or 1/10503 Note: AD_count = (Vin*Gain/1.25) * 32768+32768.
