I/O complement and supply
The VW3A58202 adds one differential analog input (0…10 V DC, 24 V, 30 kΩ impedance, 10-bit resolution) and one analog output (0…20 mA, 500 Ω impedance, 2 ms sampling, 9-bit + sign) to an Altivar 58 drive. Two assignable logic inputs (24 V DC, ≤30 V limits) and one assignable logic output (24 V DC, 12…30 V, 0.2 A max) round out the channel set. The card draws under 0.01 A from the 24 V DC internal supply (21…27 V range), with a separate 10 V DC (9…11 V) rail for logic inputs. The supply includes overload and short-circuit protection via a 1…10 kΩ impedance path.
Connection and protection
Termination is via a screw terminal block accepting 1.5 mm² / AWG 16 wire. Reverse polarity protection is provided on the digital inputs, and short-circuit protection on the output. The open-collector output is rated for 100,000 electrical cycles, with a minimum switching current of 5 mA at 24 V DC.
