8.2.4 Setting the number of AIs in IDEC SmartRelay
FL1F-H12RCE/B12RCE and FL1F-H12SCD support up to four onboard inputs that can be
used as either digital or analog inputs (0V to 10V). Inputs I7 (AI1) and I8 (AI2) are available
as analog inputs by default, whether you use them or not. Inputs I1 (AI3) and I2 (AI4) are
optional analog inputs. IDEC SmartRelay provides a menu where you can choose to use two
analog inputs (the default, AI1 and AI2), or four, or even zero. Regardless of the settings,
inputs I1 and I2 can be used as digital inputs. To use them as analog inputs AI3 and AI4, you
must set the number of analog inputs to four. Note that the number of configured analog
inputs on IDEC SmartRelay affects the subseuent numbering of analog inputs on attached
expansion modules (see the Maximum setup with expansion modules (Page 17) topic).
ou can set the number of AIs in programming mode only.
