The RM4-IV, RM4-IVT, RM4-IVH, RM4-I4 & RM4-V4 form a range of DIN rail mount instruments that accept DC analog inputs. The RM4-IV accepts inputs of 0-20mA, 4-20mA, ±100mV, ±1V, ±10V or ±100V. The RM4-IVT accepts the same range of DC analog inputs and has totaliser functions. The RM4-IVH offers high precision and high speed. It is a modification of the RM4-WT load cell/strain bridge input instrument. The RM4-I4 is a scanning/arithmetic instrument with 4 inputs. These inputs can be ±20mA or 4-20mA. The RM4-V4 is a scanning/arithmetic instrument with 4 inputs. These inputs can be ±1VDC or ±10VDC. The instruments can be programmed to perform a range of arithmetic functions on the 4 inputs. The results can be displayed and the instruments can scan and display the inputs. All the RM4 range are available with a wide variety of power supply and output options.
