Do not exceed 128 inputs total. Only 48inputs may be used for control. All modules accept T/Cs,current and voltage inputs. Only differential input modulesaccept RTDs. The high isolation modules provide240VÅ(ac) protection between inputs and 120VÅ(ac)protection between input and ground. Each moduleincludes an analog input terminal board with T/C/linearvoltage keys (PPC-AITB-1). For other sensor input keys,see the special inputs section below.Analog Input Modules (with AITB)1 = 16 channel module, differential inputs (PPC-2021)2 = 32 channel module, single-ended inputs (PPC-2022)3 = 4 channel high isolation module,differential inputs (PPC-2023)4 = 8 channel high isolation module,differential inputs (PPC-2024)5 = 16 channel high isolation module,differential inputs (PPC-2025)Analog Input Cable(Cable from module to terminal board)1 = 3 foot cable (CA-SCSI-3)2 = 6 foot cable (CA-SCSI-6)PPC-SIKX - PPC Special Input KeysOrdering InformationTo order, <strong>com</strong>plete the model number on the right with the information below.P P C - S I KEach analog input terminal board shipsconfigured with T/C sensor keys (this keycan be also used for linear voltage).
