What are the significant differences between AA/A 2.1.2 and AA/S 4.1.2?
- The AA/A 2.1.2 is designed for surface mounting. The actuator possesses two voltage outputs (0-1 V, 0-5 V, 0-10 V, 1-10 V). No auxiliary voltage is required.
- The AA/S 4.1.2 is an MDRC product for installation on a DIN rail. The actuator has voltage outputs (0-1 V, 0-5 V, 0-10 V, 1-10 V) and current outputs (0-20 mA, 4-20 mA). An auxiliary voltage of 100-230 V is required.
