The TSi3 #A-2181-0465 is to be used with HPMA and HPGA. TSI 3 units are DIN rail-mounted and feature an ‘Easy fit’ location mechanism.
There are two primary configurations of interfaces supporting lathe arms. The TSi2 and TSi3 deliver OCT (active high) output for probe status and arm positions, while the TSi2‑C and TSi3‑C interfaces deliver SSR solid state relay outputs for probe status and arm positions. The TSi2 and TSi2-C support the HPRA and HPPA lathe arms. The TSi3 and TSi-3C support the HPMA lathe arm.
