Delta RMC151 - Manual (Page 650)

RMC70/150 and RMCTools User Manual
• ±10 V and 4-20 mA input ranges
• 8 times oversampling
• One +10 V exciter output per axis
• One ±10 V, 16-bit control output per axis
• Current output up to ±200 mA with VC2124 converter option
• Can be used for controlling position, velocity, pressure, force. Can also be used for
dual-loop control such as position-pressure when used in conjunction with the AP2
module.
Part Number
The part numbers of the Analog AA modules are AA1 and AA2 for the 1-axis and 2-axis
versions, respectively.
For example, RMC75E-AA1 is an RMC75E with a one-axis AA1 module.
